UC0CLK function takes precedence over UC0STE function. If the pin is required as UC1CLK input or output, USCI0 is forced to 3-wire
SPI mode if 4-wire SPI mode is selected.

Default after reset (PUC/POR)
(5)
Setting the ADC10AE0.y bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when
applying analog signals.
